Which exerts gravitatinal pull on the earth the sun or the moon?

The larger the object, the greater its gravitational pull. Therefore, the earth's gravity is considerably stronger than the Moon's. Because the moon is smaller, it accelerates at a faster rate due to the larger gravitational pull of the earth.

∙ 9y agoThe Earth and the Moon attract each other gravitationally. To figure out the actual acceleration, use the formula:
ma = F = G*M*m / d*d
In words, the moon's mass times its acceleration is equal to the force on the moon, which is equal to the universal gravitational constant times the mass of the earth times the mass of the moon, divided by the square of the distance between the two bodies.
If we divide both sides by the mass of the moon we get:
a = G*M / d*d
Note that this means the mass of an object has no effect on the acceleration of the object due to the force of gravity. Any object orbiting the Earth at the same distance as the Moon would experience the same acceleration as the Moon does, whether the object has the mass of a banana, an astronaut, or a black hole. The Apollo astronauts tested this with a feather and a hammer on the surface of the Moon, and the feather and hammer hit the Moon at the same time.
Once we have the equation, we can use the values we know to find the acceleration. Using:
- The mass of the Earth = 59.8 x 10^23 kilograms
- The distance between the Moon and the Earth = 3.75 x 10^8 meters
- The universal gravitational constant = 6.67 x 10^-11 N m^2/kg^2
a = 0.0028 m/s^2
This is much less than the 9.8 m/s^2 we feel at the surface of the Earth.

How do tides change on Earth?
the penguins in Antarctica swim around in the sea and are very strong, so they pull and push the tides till all over the world.
Why does tides happen regularly?
Because of the way the moon goes around the Earth and exerts a gravitational pull on the oceans.
Is the pull of gravity between the moon and the earth keeps the moon orbiting the earth?
yes, earths gravitational pull is strong enough to pull the moon into orbit around it.
How far from the earth is the gravitational pull of the earth the same as the gravitational pull of the moon?
i dont now
Why does the moon make tides?
Just as the moon orbits the earth because of the earth's gravitational pull, the moon has its own gravitational pull. While it isn't enough to greatly affect the Earth's movement, it does affect the earth's oceans.
What are the basic cause of ocean tides?
Tides form due to variations of gravitatinal pull between earth ,moon and sun.
What is dependent on gravitational pull?
Any two objects with mass will have a gravitational force. The orbit of planets around stars depends on the gravitational pull of the star. The Earth exerts a gravitational pull on its moon but the moon also exerts a pull on the Earth.
Earth exerts a stronger gravitational force than the moon because Earth has more?
gravitaional pull
What exerts a strong pull on water in the ocean?
The Moon's gravitational pull on our planet causes the ebb and flow, (rise and fall), of our earth's oceans.
How strong is the earths moons gravatational pull?
The moon exerts a gravitational force approximately one sixth of the gravity of earth.
What substance on earth does the gravity of the moon have the greatest pull?
The moon's gravity exerts that same amount of pull on all substance on Earth, regardless of what it is made of. We observe a greater effect on water because it can flow freely in response to that pull, not because it is pulled with greater force.
What is the reason for moon's circular motion around the earth?
Earth exerts a pull on the moon, which keeps it orbiting the Earth. Since the Earth is so big compared to the moon, it pulls the moon toward it. In a sense, the moon is falling towards the Earth, but since the moon is also moving forwards, it ends up going around and around the Earth.
Explain the effect the moon has on the earth?
The moon, as a body of large mass, exerts a pull on the Earth as it orbits it. Earth as well exerts a pull on the moon. However the Moon is a solid body, while the Earth has a mostly-water surface, and a magma undersurface. As the Moon orbits the Earth and pulls at it, it causes the ocean, directly above it, and also on the exact opposite side of the Earth to swell upwards toward the Moon. This pulling upwards, causes low tides on shorelines. When the Moon has moved sufficiently along its path, the ocean stress releases and we get high tides. The Moon is also suspected of being a causative agent in earthquakes, since merely a small pull can be enough to cause the built-up tectonic stress to suddenly release.
Why is there a high tide on the side of Earth that is closest to the moon On the side furthest from the moon?
All matter exerts a gravitational pull on matter around it. The moon has a large enough mass to not only set itself in orbit with the earth, but also pull the water of the earth closer to it. This causes the spring and neap tides at full and new moons.
Why does center of rotation for the earth-moon system is within the earth rather than between the earth and moon?
Because the earth exerts far more gravitational pull (due to it's much higher mass) then the moon, however the moon's gravitational exertion is measurable on the earths surface in the form of tides in the ocean.
How do tides change on Earth?
the penguins in Antarctica swim around in the sea and are very strong, so they pull and push the tides till all over the world.
Can the Moon's phases cause shifts in earths plates causing earthquakes?
The Moon exerts a gravitational pull on the Earth, which causes ocean tides. If the tectonic plates were such that we were on the verge of an earthquake anyway, maybe the moon's pull could be the straw that breaks the camel's back, so to speak.However, when we take of the phases of the Moon, that refers to the way the light from the Sun hits the Moon, affecting how much of it is illuminated as we look at it from Earth. that doesn't affect the gravitational pull.
